Upper Facial Anatomy

Key vascular anatomical structures in the upper facial region and their anastomoses and interconnections must be understood and include the supraorbital and supratrochlear arteries, which are the terminal branches of the ophthalmic artery originating from the internal carotid artery, and the superficial temporal artery, which is the terminal branch of the external carotid artery.[11] Key nerves in this region include the supratrochlear nerve, which runs with the corrugator muscle and under the frontalis fascia to innervate the medial and central forehead, and the supraorbital nerve, which exits from the superior orbital foramen or notch and runs under the frontalis fascia to innervate the anterolateral forehead and scalp.[11]
